This is the first 8TB hard disk drive we’ve reviewed at Mac|Life and the biggest external (single-drive) hard disk currently on the market. It uses a new technology called SMR (Shingled Magnetic Recording) which allows the cramming of more bits on a given surface by using a similar technique to how roofers lay tiles. Drives that use SMR have one flaw — they do not perform well when it comes to sustained, random writes. They do, however, excel when it comes to sustained read speeds and burst write speeds, so they’re ideal for backup.
